Repairing our Jenn-Air Oven - Oven no heat

A couple of days before thanksgiving, the small oven of our Jenn-air oven/range broke. When the oven was turned on,  the oven light was lit but no any heat or noise came out from inside the oven. Imagine I need it to host the thanksgiving dinner for the family in next few days!

I open the small oven, removed all the shelves and the bottom cover to expose the inside, I saw the igniter lying on a metal rod. When I turn on the oven, the igniter does not lit up at all.

I flipped the breaker circuit of the kitchen area (it's hard to reach the power outlet of the oven which is located behind the oven, so we have to power down the whole thing).

Then I tried to unplug the igniter to test the continuity but it's really hard to reach the socket. After struggled quite a while, I managed to remove the black wire on the upper part of the socket but just couldn't get another one out. I even broke the plastic cover of the wire by pulling and squeezing too hard.

Igniter in the oven

That's when my husband stepped in and pointed out that I might try open the front bottom cover and gain access from there, which I did.  Thanks god, it's much easier to do from there, I unplugged the igniter, get it out, ask my husband to test the continuity with multi-meter. He told me no continuity. I feel lucky that we knew the igniter was the cause. (I learned that most of the gas oven problem are due to the defect of the igniter from internet.)

Remove the front bottom cover to access the wiring of igniter

Next, we will need to search the part online. There was no part no. printed on the igniter. I found the model no. of my oven from the sales contract which is Jenn-air PRG4810NP. After some search, we found the part we need from amazon for $22 (that's universal one, the authentical one cost over $200)

The broken igniter

The new igniter arrived after 3 days. My husband test the new part, the continuity reading is 0 Ω,(According to the youtube video, the range of working igniter resistance reading is 0~1300 Ω). We replaced the igniter and it worked! Horray!





I learned how to test the igniter from this video:

一个月前小的oven又开始不正常了。预热很慢， 并一直达不到预热温度，并且也没有开oven 后“轰”地一声响。ignitor 有变红，温度最终也能挺热（二十分钟以上）。查了一下网上，应该还是igniter 又不好了。正常情况下应该加热六七分钟就能达到预热温度了。又在Amazon上订了一个igniter, $25 before tax. 这次修理不到一个小时。补充一下细节。

只需要拿掉两铁架下边靠门口的螺丝就可以了，不需要移除上边和里边的螺丝，就可以把下面的tray取出，看到igniter.

买来的部件没有配夹线插头，需要自己有。

才知道这是第三次换ignitor 了，大概每五年换一次。
